I didn’t want to continue to hi jack the other poster, but these thought factory posters have been a life long and expensive passion of mine

Here is the original Superman pose before someone repainted the head for the final release
Like I said I’m missing a few , Thor, Capt Marvel, and Capt. America
But have the rest , I’m pretty certain the same artist did Wonder Woman and Thor, but unsure of who it was

Do we know that someone else did the final head or did they give Struzan a chance to do it himself?

Thor doesn't quite measure up but Cap is fun, and Diana's cute.

Here is another look at the Superman poster. On the right is is Drew's painting on canvas of Superman
On the left is his Poster, the Face was done by another artist though.
And here is Drew's Spiderman pencil art and the finished poster. Also his original Wonder Woman concept. the poster was done by another artist though. Drew lost out on doing her

Yeah, I'm not digging his Wonder Woman so much. Probably just as well they went another direction. Also is it just me or does "her" symbol on the left look like the "S.H.I.E.L.D." logo?

Interesting that DC seemed more willing to go bold with their interpretations, whereas Marvel stuck closer to the traditional "comic" look. Spidey in particular goes from a "real guy in a bodysuit" look in the draft to a standard Romita pose in the final. And Cap is just a Kirby cover pose (issue #193) with a paint job.

In a way, the Struzan stuff prefigures the Alex Ross material that would have fans all agog two decades later.

Superman has been totally repainted... the pose and lighting have been preserved, but they've subdued the J.C. Leyendecker styling that Struzan incorporated in his original painting. It's an intriguing approach, but doesn't make a cohesive poster with the comic strip and logo elements.
